Doctors have long known that viral infections can bring about asthma attacks and the shortness of breath, coughing, and wheezing associated with them.

There is no evidence that increasing the dose of inhaled corticosteroids at the onset of an asthma exacerbation, as part of a patient-initiated action plan, reduces the need for rescue oral corticosteroids. This is the conclusion of work published in The Cochrane Library this month.

Food allergies are more common among people with asthma and may contribute to asthma attacks, according to one of the most comprehensive surveys of food allergies ever undertaken. National Jewish Health Associate Professor of Pediatrics Andrew H. Liu and his colleagues also report in the November 2010 Journal of Allergy and Clinical Immunology that food allergies are more prevalent among children, males and non-Hispanic blacks.

An international study looking at DNA from over 26,000 people has identified several genetic variants that substantially increase susceptibility to asthma in the population. The findings, published in the New England Journal of Medicine, will help scientists to focus their efforts to develop better therapies for the illness.

A drug commonly used for the treatment of chronic obstructive pulmonary disease (COPD) successfully treats adults whose asthma is not well-controlled on low doses of inhaled corticosteroids, reported researchers supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.

Even children of a healthy weight who have an imbalanced metabolism due to poor diet or exercise may be at increased risk of asthma, according to new research, which challenges the widespread assumption that obesity itself is a risk factor for asthma.

There is no apparent link between asthma and tooth decay, according to a study published in the September 2010 issue of the Journal of the American Dental Association.

Scientists believe that a commonly used drug by asthma patients could assist in the treatment of multiple sclerosis when given alongside standard medication.

Asthma is the most common chronic lung disease of children, with more than 6.6 million affected in the U.S. Although relatively few children have severe asthma, they account for almost half of asthma related expenditures.

If you are suffering from asthma, there is every chance that watching a violent act or scene in the neighborhoods could enhance the chances of the person having to be hospitalized with breathing-related problems or any other emergencies, a new study has found.

Yale University researchers have identified three genes containing genetic variations that appear to increase a child's risk of developing asthma. The findings will be published in three separate journals: the Journal of Allergy and Clinical Immunology, Human Heredity and Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis.

Patients with asthma who are exposed to violence in their community are at an increased risk for an asthma-related hospitalization and emergency room visits for asthma or any cause, according to new research from the University Of Pennsylvania School of Medicine.
